SUBJECT: MILLSTONE POWER STATION - NRC PROBLEM IDENTIFICATION ANDRESOLUTION INSPECTION REPORT 05000336/2006006 AND

05000423/2006006

Dear Mr. Christian:

On March 3, 2006, the U. S. Nuclear Regulatory Commission (NRC) completed a teaminspection at the Millstone Power Station, the enclosed report documents the inspectionfindings, which were discussed on March 3, 2006, with Mr. J. Alan Price and other members of your staff.This inspection was an examination of activities conducted under your license as they relate tothe identification and resolution of problems, and compliance with the Commission's rules and regulations and the conditions of your operating license. Within these areas, the inspection involved examination of selected procedures and representative records, observation of activities, and interviews with personnel.On the basis of the sample selected for review, the inspectors concluded that in general,problems were properly identified, evaluated, and corrected. There were five Green findings identified during the inspection: three associated with ineffective problem identification, oneassociated with prioritization and evaluation of issues, and one associated with ineffective corrective actions. The three findings associated with ineffective problem identification included the failure to perform evaluations for boric acid leaks, failure to include acceptance criteria in turbine-driven auxiliary feedwater pump maintenance procedures, and the inadequateevaluation of the suitability of a charging pump discharge dampener modification. The findingassociated with prioritization and evaluation of issues included failure to evaluate and correct turbine-driven auxiliary feedwater pump governor control valve stem binding problems thatresulted in overspeed trips. The finding associated with ineffective corrective actions included the failure to implement effective corrective actions associated with repetitive leak rate testing failures of a containment isolation valve. These findings were determined to be violations of NRC requirements. However, because oftheir very low safety significance and because they were entered into your corrective action program, the NRC is treating these findings as non-cited violations, in accordance with SectionVI.A.1 of the NRC's Enforcement Policy. If you deny these non-cited violations, you shouldprovide a response with the basis for your denial within 30 days of the date of this inspection report, to the U. S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555-0001, with copies to the Regional Administrator, Region I; the Mr. David A. Christian2Director, Office of Enforcement, U. S. Nuclear Regulator Commission,Washington, D.C. 20555-0001; and the NRC Resident Inspector at the Millstone Facility.In addition, examples of minor problems were identified including the failure to retain qualityassurance records and performing post-maintenance testing on a safety-related component using a minor work control procedure. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, itsenclosure, and your response (if any) will be available electronically for public inspection in theNRC Public Document Room or from the Publicly Available Records (PARS) com ponent ofNRC's document system (ADAMS). ADAMS is accessible from the NRC Website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
